Top Questions We Get About Generator Installation

Living on the beautiful Alabama Gulf Coast means enjoying mild winters and sunny skies, but it also means respecting the power of Mother Nature, especially during hurricane season. For any resident of Daphne, the thought of a prolonged power outage is a serious concern. It means a home without air conditioning in the sweltering heat, a refrigerator full of spoiled food, and a family left in the dark and disconnected. In these moments, a whole-home standby generator transforms from a luxury item into an essential piece of equipment for comfort, safety, and peace of mind.

Deciding to invest in a standby generator is a significant step toward securing your home against the unpredictable. It is a powerful upgrade that ensures life continues with minimal disruption, no matter what the weather brings. However, it is also a complex installation that naturally comes with many questions. Understanding the key aspects of the process, from choosing the right size to knowing how it operates, is crucial for making a confident and informed decision.

What Size Generator Do I Need for My Home?

This is the first and most critical question homeowners ask, as the answer determines both the capability and the cost of the system. Standby generators are sized in kilowatts (kW), a measure of their power output, and choosing the correct size is essential for reliable performance. A system that is too small will struggle and potentially overload when you need it most, while an oversized system is an unnecessary expense. The right size for your home depends entirely on what you want to power during an outage.

There are two primary approaches. The first is an essential-loads system, which powers only your home’s most critical circuits. This typically includes items like your refrigerator and freezer, a few lights and outlets, any essential medical equipment, and perhaps one of your air conditioning units. This requires a smaller generator and is a more budget-friendly option that provides a solid safety net. The second approach is whole-home power, which is designed to run virtually everything in your house simultaneously, just as if the grid were still active. This provides the ultimate level of convenience and requires a significantly larger and more powerful generator.

The only way to determine the precise size needed is with a professional load calculation. A certified technician from 5 Starr Heating and Air will conduct a thorough assessment of your home’s electrical system. We analyze the power requirements of all your major appliances, particularly high-demand items like your HVAC system, water heater, and oven, to calculate the total wattage your home requires. This detailed analysis ensures we recommend a generator that is perfectly matched to your needs, guaranteeing it will handle the load safely and efficiently when called upon.

How Does a Standby Generator Actually Work?

One of the greatest benefits of a modern standby generator is its seamless and completely automatic operation. Unlike portable generators that require you to run extension cords and manually start them, a standby system takes care of everything for you, whether you are at home or away. The key to this automation is a sophisticated device called an Automatic Transfer Switch (ATS).

The ATS is the brain of your generator system. It is professionally installed next to your main electrical panel and its job is to constantly monitor the flow of electricity coming from the utility grid. The instant it detects a power outage, it springs into action. First, it safely disconnects your home’s electrical panel from the utility lines. This is a critical safety step that prevents power from your generator from back-feeding into the grid, which could endanger utility workers.

Immediately after disconnecting from the grid, the ATS sends a signal to the generator, telling it to start. The generator’s engine fires up, and within a matter of seconds, it is running at full speed and producing stable electricity. The ATS detects this, and then switches your home’s power source from the dormant utility lines to the live generator. The entire process happens automatically in about 10-20 seconds. Your lights will flicker off, and before you can even find a flashlight, they are back on. When grid power is restored, the ATS detects the stable utility feed, switches your home back to grid power, and signals the generator to cool down and shut off, returning it to standby mode, ready for the next outage.

Where Will the Generator Be Installed on My Property?

The placement of your standby generator is a critical decision that is governed by safety regulations and local building codes. A generator cannot simply be placed anywhere on your property. Our installation team will perform a detailed site survey to find a location that is safe, compliant, and convenient for your specific home layout.

Standby generators must always be installed outdoors on a stable, level surface. In most cases, this is a pre-cast concrete pad that we provide, which ensures the unit will not shift or vibrate excessively while running. The most important placement considerations involve required clearances to prevent the engine’s exhaust fumes, which contain deadly carbon monoxide, from entering your home. National and local codes mandate that a generator must be a specific distance away from any windows, doors, and fresh air intakes for your HVAC system.

There are also clearance requirements related to your property lines and, in some cases, noise ordinances to consider. The generator must also be accessible for our technicians to perform future maintenance. The experts at 5 Starr Heating and Air are well-versed in all local Daphne and Baldwin County codes. We will work with you to find a location that meets every safety requirement while being as unobtrusive as possible.

What Fuel Do Standby Generators Use?

Unlike portable generators that require you to store gasoline, residential standby generators are permanently connected to a stable fuel source, allowing them to run for days or even weeks without refueling. The two primary fuel sources for home installations are natural gas and liquid propane (LP).

Natural gas is by far the most convenient and common option. If your home is already supplied with natural gas for appliances like a furnace or water heater, the generator can be connected directly to your existing gas line. This provides a virtually unlimited fuel supply, meaning your generator can run for as long as the outage lasts without any need for refueling. It is the ultimate “set it and forget it” solution.

If your home does not have access to a municipal natural gas line, liquid propane (LP) is the ideal alternative. This requires the installation of a large propane tank on your property, which the generator will draw from. The size of the tank will determine how long the generator can run before a refill is needed. We will help you select a tank size that provides an adequate runtime for a typical extended outage in our area. The tank is then refilled as needed by a local propane supplier.

What Kind of Maintenance Does a Generator Require?

A standby generator is a significant investment in your home’s security, and like any major mechanical system, it requires regular maintenance to ensure it will operate reliably when you need it most. A generator is essentially an engine, and just like your car, it needs periodic service to stay in peak condition.

Most modern generators are designed to help with this process by performing a weekly self-test. For about 10-15 minutes each week, the generator will automatically start and run without transferring power to the house. This brief exercise circulates the engine oil, charges the battery, and confirms that the system is ready to perform. It is a reassuring sound that lets you know your protector is standing guard.

In addition to this self-test, professional annual maintenance is essential. A certified technician from 5 Starr Heating and Air will perform a comprehensive tune-up, which includes changing the oil and oil filter, replacing the spark plugs and air filter, testing the battery, and inspecting all belts, hoses, and electrical connections. We will also test the function of the automatic transfer switch to ensure every component is in perfect working order. Enrolling in a maintenance plan is the best way to protect your investment and guarantee that when the lights go out, your generator will be ready.

A whole-home standby generator is more than just a piece of equipment; it is a powerful source of security, comfort, and self-reliance in a region where power outages are an unfortunate fact of life. The ability to keep your air conditioning running, your food fresh, and your family safe during and after a storm is an invaluable asset. From selecting the perfect size and fuel type to ensuring a code-compliant installation and providing long-term maintenance, every step is critical to creating a reliable system.
